The reaction N2(g) + 3 H2(g) → 2 NH3(g), does not favor formation of products at room temperature but does favor formation of products at a much higher temperature. What can you conclude from this about the signs of ∆H° and ∆S°, assuming that the enthalpy and entropy changes are not greatly affected by the temperature change? a. ∆H° must be negative.
b. ∆S° must be equal to zero.
c. ∆H° must be equal to zero.
d. ∆H° must be positive.
e. ∆S° must be negative.
f. ∆S° must be positive.

In an exothermic reaction the bonding energy of the product is: less than the reactants same as the reactants greater than the reactants dependent upon the presence of a catalyst

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
